How To Build A GMRS Repeater - Part II - Antenna, Duplexer, Coax, Grounding, & Idiots On Youtube
HTML-код
- Опубликовано: 29 апр 2021
- More planning on building my high power GMRS repeater out of two Wouxun KG-1000G GMRS radios. In this video I talk more about using the right coax for the repeater to reduce power-loss, mounting the GMRS antenna in a location that meets my requirements, and how to properly ground the antenna - actually, there will be no discussion on antenna-grounding as there are too many morons on RUclips that will post comments with bad information about how to ground an antenna "the right way" - instead I talk about where to go to find out how to correctly ground your antenna for lighting protection as well as proper RF ground. Any comments on this video about how to ground the antenna will be removed.

Wow this old man on the youtube video does not act like adult. He act like 5 year old child. Very poor tutoría
Spell much?
I don't know, I would say Randy is a well *grounded* individual.
Exactly what country are you located in? You’re definitely not an American.
Get out of here....... lern englis befor yu coment
RANDY OS VERY COOL ,I HAVE Learned ALOT FROM HIM
I feel like I’m watching a cross between a soothing Bob Ross and an insulting Ron Swanson. I like it.
That’s… kinda dead on. And the sarcasm sometimes is killer
put a happy little radio over here and maybe a few bigger radios over here.
It’s glorious 🎉
All I will say is, that it's great to watch videos from such a well-grounded individual. Very cool to follow your progress!
you beat me to it lol I was going to say "stay grounded"
I'm happy this channel is here. It keeps me GROUNDED!🙂
You are never BORING!!!
Your videos are great. Informative and entertaining. I especially love how you set the expectation of your viewers behaving like grown-ups.
Just bought me everybody's (HAM users) favorite unit (uv5r) thanks to you. Love the knowledge you drop on here, thank you oh so kindly for dropping these gems for newbies like me. Keep it up :)
Mine came yesterday also. Now I am just waiting for the cable to use chirp
Welcome to the baofeng uv5r club
Work for everything but CB. And for God sake don't donate $35 to the agency who will use it to persecute you for breaking their rules (not laws). Stay smart.
It is admirable that you realized that you were wrong and thank those who gave you good advice.
Your videos are well-produced, informative, and entertaining. Thank you for not perpetuating any of the many myths and old wives' tales regarding grounding. It's one of those subjects which is so misunderstood by so many. The saddest part is that if you don't know anything about it, *everyone* sounds like an expert on the subject. It's hard to tell who's "got the goods" and who's faking it. At least, that's been my experience when looking for information on the subject within the ham radio community.
This is a well grounded video and thanks for all the info and tips you add.
Great video, may I mention I used to contract with a telephone company doing line work and underground and yes grounding is very important.
You got this. Glad you went LMR. 50W out the door will only give you 6.25W if you used RG-8X on a 100' run instead of UHF-rated feedline. I have that Samlex 35A power supply and although it's very good, its internal fan is horribly loud. if it's not in a living space then don't worry about it. There's a mod to run the internal fan constantly and at lower speed if you need it. Definitely add extra cooling to the transmitter if you think your machine will be heavily used, and when the CA temps hit 90 and above. The more the betterer. Good choice on the PL. Since you're running an open repeater don't forget to have it identify as needed (fast speed, low audio level Morse Code ID will suffice and you can do that cheaply if you look around, if you don't already have it covered. Don't forget a time-out timer for long-winded loudmouths or numpties who sit on their mic buttons.
Outstanding; can’t wait brother, thank you and God Bless.
Very educational and entertaining Randy. You are definitely a pillar of the GMRS community. I hope your power bills haven't gone through the roof. ;)
I just got my GMRS "WRZH956" for My Dad and Mom. I shared Randys Channel to my Dad so He can learn better from Randy. I SUCK at teaching what I Dont Really Know! My Dad is GOING TO LIKE "notarubicon" Randy!!! LOL Blessings All
Well, as usual I'm a day late but not short on the $$....regardless, it's best channel for learning stuff about things
The ARRL book on grounding and bonding is informative and easy to understand. I found it useful and I'm not an electrician.
I would say you kept yourself very Grounded in your discussion about listening to RUclips advise. I couldn't help myself
Thanks for your info...can't wait to see next show. I'm new to GMRS and enjoy all you information.
I'm eagerly waiting the repeater. I saw it posted on mygmrs the other week.
This is a very well grounded channel… nice work Randy. 👍👍
As a 30 yr electrician that has worked all over the country I concur. Most people try to make it all more confusing then it actually is. Most electricians I have worked with or even in FB groups are the most self righteous, pompous, and egotistical tradesmen out there. They over complicate things so the clients beneath them can't actually tell if they are getting a good deal or not.
Worse than welders? Those guys are quite (ahem) opinionated and won't waste a 1/2 second telling you your work is crap.
Hey, Randy, another great video, thanks for sharing as always.
Way to go LMR400! And they make 400 in ultra flex for the business end. (It bends easy, jumpers) love the channel, your attitude and the music. Big fan.
Your mileage may vary with LMR400. It doesn't play well in dull duplex (repeater) applications. It may work at first but trust me, down the road it is going to be a problem. Been there done that. When the intermod from the transmitter starts getting back into the receiver side of the repeater it all goes downhill from there.
I built my own wifi accessible temperature and humidity based fan control system before homekit was a thing. It keeps boxes of electronics (WiFi router, dog “fence” transmitters, etc…) up in the attic nice and cool all year long. It’s also saved me hundreds of dollars worth of electricity over simply running the fan full time.
Just recently got into this whole radio thing and I’m surprised to see how much controversy there is around such a specific nieche
My .20 cents: I have a 2x KG 1000G set as repeater with Nagoya NMO-200C antena, only isue I had to solve was TX hang up in transmission (radios are on top of each other using short cable). Solution: 6"x9" brass plate between radios and brass tape wrap around short connection cable. Either one work by it selves, but I am using both.
If it's the right distance another repeater on same pair is always a bonus if both can stand another and the use. Increases range
Congrats ! MyGMRS has a listing for your new repeater.
my kids r grounded after this video for sure 👍🏻😂love your videos
Did somebody say something about ....ground..... well, I thought ground was dirt or something like that. I think RUclips has a lot of dump truck channels... might find some dirt there. Dirt, gravel and that kinda stuff.... But if a hard wind comes along some day, that antenna might find itself down on the g****d. Oops, almost said that g-word.. Love the channel man. Keep it up.
Keep of the great work man can't wait to see if I can hit your repeater from yucaipa.
I’m all over this as I’m doing the exact same thing 👍🏻
Dude - you are MUCH too entertaining to unsubscribe!
@1:39 You sir are NOT BORING AF :D
Thank you for making me your favorite viewer.
Thank YOU!
my mom used to ground me when i was a kid...but id jump out the window on to the ground...once i was grounded i hit the ground a runnin ;) always get a smile and a laugh from your videos thought id try n give back in my own stupid way
Keep your lighting suppression parts outside of the house. All of it. This is the whole reason for doing it. And even then sometimes it just doesn't work as planned. But it's better than nothing.
Bingo thought i was close to ya, Fontana. Way cool 😎
In all seriousness, I want to thank you for calling out the sad Hams and BS'ers. I think you a re providing a valuable service and I am a huge supporter of you. I hope to meet you someday.. Thanks for the repeater vids, I am building one in northern San Diego county. Would you care to hear comments on how it is going? Glenn N6JAI
Well Grounded Video...
I’m back in class to learn.
The only ground I'm interested in is coffee!
Thank you very much
good stuff. there is info on the the subject you don't want to discuss in the armature radio tech test.. test questions available at the ARRL website or online ham radio study courses. use their info or not, it's up to you.
Can you please do a video on the current repeater you setup and how you connected to the Zello network
Thank you
chances are that many of the helpful comments came from ham radio operators who take their hobby seriously and their experience benefits you and your channel.
The very few actual helpful comments do benefit me, my channel and my viewers. The other 98% only benefit the ego of the morons leaving the comments.
Love it thx
Since you have mountains behind you. Did you consider using a directional type of antenna?
Hello, I am a fairly new GMRS “Dork” and just received a Wouxun KG-1000G and a DWC30WIN power supply. I will also be using a Ed Fong antenna mounted on my roof that WILL be grounded!!! So I wanted to know what type of lighting surge protector you are using and where to place it within the setup? Thanks for all of the helpful advice in your videos and love your sarcasm so much so that I set up my squelch tail to last the longest for those HamBones.
I to live here in the “IE” at the top of Fontucky, thanks again for your advice.

Very good educational video and you've inspired me to get into GMRS. I'm not quite sure how much the sections for the Rohn triangle towers cost these days, however, these come in 10 ft lengths and just two of those would get your antenna up to a decent height and with a good base, it'll be freestanding. If you check a local hamfest, you just might get a bargain.
I went from losing you to become a small sponsor. Woot!
You are cracking me up!
Thanks!
Thank YOU!
When using the radios like this, does that make them dedicated to only be used as a repeater or can you still use one as a base?
I built an off grid wireless network for a community in Pa with a 200 ft tower on top of a mountain and the grounding was the most stressful part of the whole project.
Randy what is the energy usage of your set up? I intend to set this exact system up up but I the site is somewhat remote so I need to power it with a solar panels and batteries. Any guidance you can provide would be appreciated.
You could get a antenna tower to mount your base antenna
This video seems well grounded….
With all the equipments you got sir, how much distance your repeater will cover under normal conditions?
Sir question what other antena would you recommend the one in the link is not in stock at the moment?
Thanks
Hey “princess notarubicon sparkle pony”, the only question I have is it POSSIBLE to also use a radio antenna pole AS a light pole also? Or, use a light pole as a base to mount the radio antenna? I have a hill close to my house in the country and already have the light pole in the pasture. Watching ur channel makes me want to install a repeater station too.
Thanx!
I prefer to use a GMRS antenna so don’t have to tune it. Any recommendations for a high gain GMRS antenna?
How about lightning arrestor? Do you need that? Or just grounding is enough? For external wifi yaggi's we had to use lightning arrestors on the coax...
Awesome! I’m literally doing the same thing with the same radios and the same power supply. I mounting mine in a small server cabinet from Amazon in the garage. My God great minds think alike. I really want to talk about gr gr gr gr grrrr......
You're grounded!
In each video, please put a link to the subsequent video - YT doesn't make it easy to find them.
You're grounded!
I was grounded once, I learned my lesson. lol
My house is on a slab. So I can kick off my shoes and ground all year long. Very good for bloodflow. That's all I have on grounding.
Make sure when you ground the antenna you.... jk 🤣
That mobile duplexer will get interference if close to other electronics. Also that's not the highest gain antenna, a good antenna is a folded dipole.
im liking your videos more and more, studying to be tested for my ham license . it rough but im fighting to make it better, . learning is good, one day at a time, thank you for your information , but getting back to studying for my test. repeaters ? license first , repeater 2nd. there is 1 question , on radios in the future, wouxen grms radio model uv9g pro , ids this a good radio to start with as a handheld. or ???
the UV9G Pro is a great radio, with a lot of features, but there are also other radios that are less complicated, so it just depends on what you want to do with the radio.
@notarubicon could you use a mobile with a full duplexer like an AnyTone AT-5888uv to make a repeater? The website said it has crossband, UU, UV, VV, and VU repeating capabilities.
I put a couple walkie talkies together with a patch cable. Note: don’t have the receiving radio at full volume or you will fry the transmitting one, blow out everyone’s speakers, and dispense copious amounts of tinnitus. Ending the lives of 3 uv5rs. Baofengs are great to experiment with as I’m only out $35. Imagine if I used 2 of my Q10s. That would be almost $450 down the drain……… now for a moment of silence for the 3 uv5rs……………………….they won’t hurt anymore. Besides, their deaf now so it’s more then a moment of silence for them.
Randy, I am brand new to GMRS. Your videos have been amazingly insightful, thank you. I do have a question. I want to put a tower up for a base radio, i also want to add a repeater to my property. Can these be done on the same tower or is there a minimal distance i should have between them? Thank you in advance!!
Yes, you will need a lot of separation - vertical separation is best but if they are running on the same frequency, your tower may not be big enough. There are calculations to tell you how far apart they need to be based on the type of antenna and the frequencies.
Putting your own repeater together is better than buying one made up. First, I think that the Wouxon radios are about the best GMRS radios made. I own a 905 and a 935. You'll be using higher quality everything that the preassembled ones since they might cut corners to keep the price down. It looks like you've done your homework also on that thing we can't mention. Now off to watch the rest of your video's, since I will build one too.
It sounds like you live here in Arizona. I live in Apache Junction.
Were did you get the Rf grounding And Spark Arrestor and Ground Strap Randy? 13:00 oh I see why you didn't post a links or talk about it My bad sir @NotaRubicon Productions
? I'm running a 50w base, I use a repeater 12 miles away and get about 25miles.. but.. I'm at the very edge of its range. And would like to transmit more fars south of me ,if I put the repeater at my house, won't that just give me the same fars I have now with my base station? I'm thinking I should put it up about half as fars away from me..At a other location] and get way more fars?
@wilbertonoriega… your posted comment about Randy is ridiculous and wrong. Randy is very knowledgeable . His RUclips videos are not only helpful but they are also extremely hilarious . If you don’t find him helpful and you don’t understand or like his sarcasm, then don’t watch him. No one is forcing you to watch his videos. Go find someone else to watch. And take the rest of the SadHams with you. As for me, I will continue to watch him. I will seek his help and will continue to enjoy his sarcasm. Thank you Randy for all that you have done. Keep up the good work.
The only thing that gets me is that one radios transmitter will never be used. Is it possible with that setup to have another repeater operating in reverse on two channels or the unused one operating a simple repeater. Any more info on what options the have built in the radio using the interlink
My suggestion would be either switch out the Tx Rx radios or just let them be and if you have a Tx or Rx part failure you already have a backup part.
What items does one need to connect the GMRS Duplexer to the radios? All items used would help. (Short cables with proper ends, what the cable #s are and any other connectors need.) Thanks, Marc
You need some good quality (ie, not cheap) short coax patch-cables.. The exact connectors depend on what duplexer you use, but because some duplexers have "N" connectors, you may need patch cables with PL259 on one end (from the radio) and "N" type on the other end. You will have to look at the holes on your duplexer and the holes on your radio to determine the exact connecters you need.
This is all part of the learning experience.
👍✌
I’m having. Trouble getting my base station set up . Everyone that I talk to tells me deferent on what I need .
A grounding rod is supposed to be 7' feet and 3/4 inches. LMAO
Delete DEEz Nutz !!!
Just kidding love your videos and humor.
If you put a tone can you and another person have the same freq?
The coax I use is Italian made messi and pelosi HYPERFLEX 13 /.500. way more than needed but they sell awsome connectors too. If you want no excuses stuff it's great.
😂 I love the sense of humor
Got a dumb question. When tuning the 1486 tram antenna, do you have to cut the 3 steel radials at the bottom? Like you would for a car antenna? Thanks! Great videos.
@@TheNotaRubicon thank you sir
sorry, i just re-read your question - the radials do NOT need to be trimmed.. but you do need to remove the antenna elements (wire) from inside the PVC and cut THOSE.. again, the instructions are pretty clear/understandable..
@@TheNotaRubicon no problem. Thanks
This may have been asked before, but is there any way you can link/daisy chain gmrs repeaters? I drew it all out of a piece of paper and no matter how i configured it, it wont work.
Short answer: NO, not over the air on GMRS
I want to donate crap tons of money to your channel.....But I don't have that 😣 so.... 👍👍😁! And thanks for the great content.
Could you use a tree as part of your antenna system?
👍🏽👍🏽
Where do you get your T-Shirts?
Great video. How do we find you on Zello? Thank you.
Zello info here: www.notarubicon.com/zello-gmrs-repeater/
Did you have to tune the duplexes? Glenn
Duplexers do need to be tuned, but if you buy one from BuyTwoWayRadios they tune it for you.
I feel like a sad ham. This Tram 1486 tuning SUCKS. PLZ HELP. The cutting chart is different from the one online. What mm did you end up with on L1 L2 & L3??????? Swr is good at 5 watts but at 25/50 watts its 1.9 on repeater channels & 15-22. Also my btech 50x1 only shows 23 watts on high.
Sorry, the antenna is all back together and in the air, and i tossed the chart after i got my (near perfect!) SWR..
If on High Power Setting, on a repeater channel/high power channel (Ch 14 or higher) you are only getting 23 watts, then check your meter and test with a dummy-load instead of an antenna. If it still only gives you 23 watts, call Btech and tell them to send you want that does what the box says it will do.
@@TheNotaRubicon Thank you.
p.s. I wish you'd do videos like this on Jeep-related tech. I'd pay to see you get this in-depth on regearing or dropping in a 4" lift and beefier suspension kits. Much more fun than radios, which is why my 41 year radio habit is taking a back seat to 4x4 'wheeling and overlanding. Looking for a unicorn rust-free TJ to build up and run 35s on.
Is everybody else within the 25 miles that you want to reach, also 2000 ft. above sea level? Height is probably the best "force multiplier" outside of an ampliafier.......and they are expensive!
No.. Most of the area is in the valley - ranging from 400 to 1000 feet below..The repeater is now up and operational - not only is it covering the entire range we had hoped for, we are getting contacts from (so far) up to 45 miles away, from spots we never thought possible, mostly areas in the mountains above us.
ARRL? You're slowly coming to the dark side....wahahahaha
Did you had to calibrate the duplexer for the frequencies you needed?
Mine came pre-tuned.
@@TheNotaRubicon I bought one on amazon, needed to return it
@@TheNotaRubicon Did you contact them to calibrate for you? I am building my own GMRS repeater
I bought mine from BuyTwoWayRadios.com and if i recall they have the option to pay a few more $$ and you tell them what frequencies you will be using and they tune it.
@@TheNotaRubicon thanks for replaying, mentor. I will send them an email about it
